The object of this invention is to provide an apparatus allowin of jointing the ends of the films by a sing e operation, in which the apparatus cuts the ends of the films, wets them with a suitable preparate, 'for example with acetate of amyl, and exerts 'the pressure required to obtain the joint.

In order to avoid the need of removing the emulsion from the end of one of the films, it is possible to arrange an independ ent strip of film on the adjoining ends of the films, instead of causing one end to overlap on the other one.

In the annexed drawings a construction of-the apparatus according to this invention is shown, and Figure 1 is a longitudinal sectional view; Fig. 2 is a front view; Fig. 3 is a plan and Fig.4 is a side view of a modified construction.

Theapparatus comprises the stand l-carrying the shaft 2 on which is mounted to turn the hub 3' having arms 4, 5 and 6. Two

of these arms, as 4 and 5, carry an areshaped plate 7; this plate being provided with a slot 8 ending in enlarged holes 8' and carrying two knives 9. To the arm 4 extending beyond the plate? are also secured a radial plate 10 provided with holes 11 and an arm 12 for the handle serving to actuate the apparatus. An electric resistance 45 can be arranged under said plate 10 in order to heat it so as to assist the drying of the jointed parts 4). a

To the arms '5 and 6 is secured anarc shaped plate 13, provided with teeth if desired, intended to come in engagement with the friction or gearing wheel 14 solid with the gear wheel 15 which by means of the crank 16 and rod 17 causes the bar 18 to travel axially, this bar 18 being supported in 18 and carrying at'its end the brush 19.

In the front portion of the stand 1 are arranged two plates20, 20, for receiving the ends of the films on which press two spring fingers 21. These two plates, or a single one of them, can be displaced sidewise; in the latter case one of them (as 20) is normally maintained spaced apart from the other one by a spring 22 (Figs. 2

and 3) and is actuated by the suitably profiled edge of the plate 7 acting on the roller 23 mounted .on the plate 20 so that this plate is displaced to left'after the" knives have passed beyond the plane of the plates.

Each plate 20 and 20 carries also two-pins 25- intended to penetrate into holes 11-01.

the plate 10 when this latter-rests on the plates 20 and 20', in order to perforate the strip of film serving to effect the joint or simply to grasp it. This strip of film is carried by a reel 26 mounted on the support 26 of the arm 4 and is caused to unwind itself from said reel by the friction exerted by the roller 27 solid with roller 28 which is actuated by hand or by rolling on the fixed plate 29. .A' knife 30 mounted on the arm 4 is intended to cut the film strip when the plate 10 presses on plates 20, 20'.

V A small receiver 31, which if desired may be connected to a tank 32, contains "a suitable preparate, as for example acetate of army], and is carried by a support 33 under the brush 19 when the brush has'the position shown in Fig. 1, while it is lowered by the displacement of the arc-plate, 7

In the modified construction shown in Fig. 4, the displacement of the rod 18 carrying the brush is obtained by having this rod guided on supports 34' and connected to a swinging lever 35 articulated to an arm 36 which inturn is connected to a rod 37 guided in supports 38 and provided with a pin 39 intended to engage in a slot 40 in the side surface of the arm plate 81. Said slot is divided in two portions by'the swinging member 41 pivoted in 42 so that during the rotation of the arc-plate 13in one di-' rection the pin 39 is caused to travelin the direction of the arrow (Fig. 4) in a given ed are arranged on the plates 20, 20 and under the fingers 2 1, and the handle 12 is actuated so that the whole apparatus is operated. Then the knives out the ends of the films, and the cam profile 24 acting on the roller 23 approaches to each other the plates 20 and 20 and also the edges of the ends .of the films. Then the arc plate 13 comes in engagement with the wheel 14: (Figs. 1-3) or the pin 39 mounted on the inclined surface of the member 41 (Fig. at), so that the brush 19, free from the receptacle 23 which has been lowered, advances and Wets the adjoining ends of films. At this time the roller 28 comes in engagement with th plate 29 (Fig. 2) and the roller 27 causes a portion of film to unwind itself from the reel 26, which portion takes place on the plate 10, so that when this plate rests on the plates 20, 20, it presses the strip of film arranged on it, on the adjoining ends of the films to be connected and cuts the same strip by means of'theknife 30. The

pins 25 will perforate the strip if required 20 or simply grasp it. The joint is so efiected and immediately dried by the heat produced by electric resistance 4C5. Then all the members of the apparatus are caused to retake' the position shown in Fig. l by raising the handle 12 in its primitive position, and the jointed films'are removed from the pins 25 by aid of the lever 44. j
